    Abstract Diprosopus is a congenital anomaly in which partial or complete duplication of craniofacial structures occurs. Because it is rare, the mortality rate is high, and information concerning this anomaly is scarce. This study describes a case of human diprosopus in a 9-year-old male individual, who has severe complications associated with the central nervous, cardiovascular, respiratory, and digestive systems. Since birth, he has been monitored in a specialized hospital environment, where he has undergone several surgeries and multidisciplinary treatments. Regarding the craniofacial aspects, he had agenesis of the corpus callosum, floor of the nasal cavity, and floor of the anterior cranial fossa, in addition to the presence of bone dysplasia, ocular hypertelorism and cleft palate with nasal and oral teratoma. Regarding dental characteristics, the patient has duplication of the maxilla, mandible, tongue, and some teeth. After complementary imaging exams, several supernumerary teeth were found, with some being impacted and in complex regions, with an indication for extraction due to the risks of impaction, irruptive deviation, root resorption, and associated cystic or tumoral lesions. Because of the numerous complications, knowledge, and preparation of the entire team is necessary for the correct management of the case.

    Abstract Migratory shorebirds are notable consumers of benthic invertebrates on intertidal sediments. The distribution and abundance of shorebirds will strongly depend on their prey and on landscape and sediment features such as mud and surface water content, topography, and the presence of ecosystem engineers. An understanding of shorebird distribution and ecology thus requires knowledge of the various habitat types which may be distinguished in intertidal areas. Here, we combine Sentinel-1 and Sentinel-2 imagery and a digital elevation model (DEM), using machine learning techniques to map intertidal habitat types of importance to migratory shorebirds and their benthic prey. We do this on the third most important non-breeding area for migratory shorebirds in the East Atlantic Flyway, in the Bijagós Archipelago in West Africa. Using pixel-level random forests, we successfully mapped rocks, shell beds, and macroalgae and distinguished between areas of bare sediment and areas occupied by fiddler crabs, an ecosystem engineer that promotes significant bioturbation on intertidal flats. We also classified two sediment types (sandy and mixed) within the bare sediment and fiddler crab areas, according to their mud content. The overall classification accuracy was 82%, and the Kappa Coefficient was 73%. The most important predictors were elevation, the Sentinel-2-derived water and moisture indexes, and Sentinel-1 VH band. The association of Sentinel-2 with Sentinel-1 and a DEM produced the best results compared to the models without these variables. This map provides an overall picture of the composition of the intertidal habitats in a site of international importance for migratory shorebirds. Most of the intertidal flats of the Bijagós Archipelago are covered by bare sandy sediments (59%), and ca. 22% is occupied by fiddler crabs. This likely has significant implications for the spatial arrangement of the shorebird and benthic invertebrate communities due to the ecosystem engineering by the fiddler crabs, which promotes two ...

    Abstract Mangrove forests are productive habitats and major potential exporters of organic matter and nutrients to adjacent habitats. Here we examine the extent to which mangrove carbon is transferred to adjacent intertidal food webs in the second largest mangrove-covered area in Africa, in Guinea-Bissau. Applying stable isotope analysis and mixing models, we made comparisons at two spatial scales: (1) a large scale, comparing intertidal flats with (mangrove sites) and without (control sites) adjacent mangrove forests regarding the carbon isotopic signature of macrozoobenthos and sediment organic matter (SOM), and the relative importance of potential primary food sources in sustaining macrozoobenthos, and (2) a fine scale, performing stable carbon isotope measurements along 200 m transects from the coastline out to open intertidal flats, to trace mangrove carbon in macrozoobenthos and in the SOM. We found no evidence that mangrove carbon sustains intertidal food webs, despite SOM being significantly more depleted in

This likely has significant implications for the spatial arrangement of the shorebird and benthic invertebrate communities due to the ecosystem engineering by the fiddler crabs, which promotes two vastly different intertidal species assemblages. This large-scale mapping provides an important product for the future monitoring of this high biodiversity area, particularly for ecological research related to the distribution and feeding ecology of the shorebirds and their prey. Such information is key from a conservation and management perspective. By delivering a successful and comprehensive mapping workflow, we contribute to the filling of the current knowledge gap on the application of remote sensing and machine learning techniques within intertidal areas, which are among the most challenging environments to map using remote sensing techniques.

    Abstract Objectives: The involvement of adolescents in violent behaviors is becoming an important public health problem that is concerning physicians as it is associated with a decrease in adult life quality. In this context, bullying is a type of aggressive behavior that occurs repeatedly in interpersonal relationship where power imbalance exists increasing the risk of physical and psychosocial problems in all its intervenient. Prevalence of bullying in Portuguese adolescents is estimated to be ranging from 16.2 to 27.5%. Sleep disorders are a well-known problem related to bullying situations, either as a consequence or a risk factor; estimated prevalence in adolescence is 25% worldwide. In the present study we aimed to investigate the association between sleep quality and the involvement in school bullying in Portuguese adolescents in two high schools.
    Methods: Data collected from a cross-sectional survey addressing questions on bullying behaviors and sleep quality was analyzed using SPSS 22.0. A two-tailed p-value of less than 0.05 was considered significant for all tests.
    Results: We have included 171 adolescents, mean age of 14.39 ± 1.149 years, 59.6% were boys; prevalence of bullying behaviors was 28.1%. Among the students 15.2% were identified as "pure victims", 8.8% as "pure bullies", 4.1% as "bully-victims" and 71.9% as "neutrals". "Pure bullies" and "bully-victims" present higher Athens Insomina Scale (AIS) scores (p = 0.004) and higher prevalence of insomnia (p = 0.004). The prevalence of insomnia was significantly higher in the group involved in bullying behaviors comparing with the neutrals (58.3% vs 30%, p = 0.001). We verified that 65.4% of the reported bullying situations took place inside the school and 8.8% of those teachers did nothing to help the victim and in 17.5% school staff took the same attitude.
    Conclusions: We found a prevalence of bullying behaviors higher than the one reported in previous studies and a prevalence of insomnia of 38.0%, proving that bullying and sleep disturbances are two major problems in adolescence which may increase future risk for psychiatric symptoms, involvement in criminal activities, hyperactive, and inattentive behaviors. We verified a strong relation between insomnia and involvement in bullying situations with those who are involved reporting difficulties in sleep induction. The group of "bully-victims" was identified as potentially being the one with the most troubled adolescents since they combine characteristics of both bullies and victims. The authors conclude that there should be an investment in school-based interventions that help recognize and reduce school bullying and change lifestyle behaviors that may negatively influence adolescents' development.

    Abstract Mangrove forests are productive habitats and major potential exporters of organic matter and nutrients to adjacent habitats. Here we examine the extent to which mangrove carbon is transferred to adjacent intertidal food webs in the second largest mangrove-covered area in Africa, in Guinea-Bissau. Applying stable isotope analysis and mixing models, we made comparisons at two spatial scales: (1) a large scale, comparing intertidal flats with (mangrove sites) and without (control sites) adjacent mangrove forests regarding the carbon isotopic signature of macrozoobenthos and sediment organic matter (SOM), and the relative importance of potential primary food sources in sustaining macrozoobenthos, and (2) a fine scale, performing stable carbon isotope measurements along 200 m transects from the coastline out to open intertidal flats, to trace mangrove carbon in macrozoobenthos and in the SOM. We found no evidence that mangrove carbon sustains intertidal food webs, despite SOM being significantly more depleted in ¹³C in mangrove sites. Mangrove leaves had the lowest relative contribution to the diet of macrozoobenthos, while macroalgae, benthic microalgae and POM showed variable but overall relevant contributions. Yet, at a smaller scale, mangrove carbon was detectable in SOM and in most macrozoobenthos, being strongest within 50 m of the mangrove edge and quickly fading with increasing distance. Our results suggest that there is only a marginal input of mangrove carbon into the food webs of unvegetated intertidal flats. Still, this leaves open the possibility of mangrove forests acting as sources of dissolved inorganic carbon and processed nitrogen, which can be assimilated by the algae and subsequently fuel adjacent food webs.

    Abstract Background: To evaluate the influence of previous physical activity (PA) during childhood, adolescence, and current PA practice on the production of antibodies and inflammatory response between the first and second doses of the COVID-19 vaccine.
    Methods: Fifty-nine men and 56 women were evaluated before the first vaccine, and 12 weeks later, blood samples were taken to quantify production of anti-severe acute respiratory syndrome coronavirus-2 immunoglobulin G antibodies and cytokines. Previous PA during childhood and adolescence was self-referred, and current PA was assessed using the International Physical Activity Questionnaire.
    Results: A positive and significant association was observed only between PA practice during adolescence and an increase in antibody production in adulthood (β = 2012.077, 95% confidence interval, 257.7953-3766.358, P = .025). Individuals who practiced PA during adolescence showed higher production of antibodies between the first and second vaccine dose compared to nonpractitioners (P = .025) and those that accumulated ≥150 minutes per week of current moderate-vigorous PA (MVPA), and presented higher antibody production in relation to who did <150 minutes per week of MVPA (P = .046). Individuals that were practitioners during childhood produced higher G-CSF (P = .047), and those that accumulated ≥150 minutes per week of current MVPA demonstrated lower IP-10 levels (P = .033). However, PA practitioners during adolescence presented higher G-CSF (P = .025), IL-17 (P = .038), IL-1RA (P = .005), IL-1β (P = .020), and IL-2 (P = .026) levels.
    Conclusion: Our results suggest that adults that accumulated at least 150 minutes of MVPA per week or practiced PA during adolescence developed an improved immune and inflammatory response against COVID-19 vaccination.

    Abstract Objective To characterize the profile and pattern of alcohol consumption in adolescents, admitted with acute alcoholic intoxication (AAI) at a pediatric emergency department of North Portugal. Methods Retrospective descriptive study of adolescents aged between 10 and 17 years, admitted with AAI between 2012 and 2016. The following variables were evaluated: age, gender, drinking context, quantity and type of alcohol, Glasgow Coma Scale (GCS), previous episodes, associated injuries, transport to the emergency department, other drug consumption, blood alcohol level (BAL), blood glucose level, treatment and orientation. The χ2/Fisher's exact test and t-Student test were performed (p < 0.05). Results A total of 180 adolescents with AAI presented. The majority of adolescents were older than 15 years old (71%) and 3% were younger than 14 years old. The mean age was 15.9 years [standard deviation (SD) 1.1 years] and 65% were males. The most common type of alcohol consumed was distilled drinks (60%). Recurrent alcohol use was identified in 7% and binge drinking was reported in 37% of patients. The mean BAL was 1.58 g/L (SD 0.6 g/L) and there were other drug consumptions (mainly cannabinoids) observed in 11% of patients. After emergency department discharge, 17% were followed at hospital consultation. There was no significant difference between boys and girls or between BAL and injuries or other drugs consumption. Conclusion This study confirms a high rate of alcohol use among adolescents, in particular "heavy episodic drinking", revealing an easy access to alcohol at this age. The integration of alcohol use prevention programs in community and education systems should be encouraged and implemented in every adolescent consultation.

    Series title Pediatric Neuroradiology
    Abstract The Ramsay Hunt's syndrome (RHS), caused by the reactivation of the varicella-zoster virus (VZV), is an infrequent cause of peripheral facial palsy in the pediatric patients. A 16-year-old adolescent boy presented with headache, right earache, and signs of lower motor neuron type facial palsy. He was medicated with deflazacort. Four days later, he developed blurry vision in the right eye, gait imbalance, and vesicular lesions in the right ear with decreased ipsilateral hearing acuity. A diagnosis of RHS was considered. Cerebrospinal fluid (CSF) analysis showed pleocytosis, as well as VZV DNA. Magnetic resonance imaging of the brain identified abnormal uptake of gadolinium contrast in the right seventh cranial nerve, reinforcing the diagnosis. The patient was treated with acyclovir (14 days) and prednisone, with progressive clinical improvement. We emphasize the importance of recognizing this syndrome in patients with facial palsy, since the early antiviral treatment significantly improves the prognosis.
